[QUOTE="Topper, post: 1094203, member: 186250"] Was given a circular saw a few years ago when a friend's father died. I have used it ever since when the need arose. Last week I spent three days building a frame over a friend's new patio and we were cutting some serious wood, 4"x4" posts and 6"x3" and the saw blade stopped driving whilst the motor was still running. Today I decided to strip it down and having spent 20 years in textile and light engineering, prior to returning to study I. T. in 1993, assumed I knew enough about engineering to be able to determine the cause and possible solution to the problem. Having stripped and cleaned all parts I was somewhat bemused when I discovered the reason for the lack of drive. Somehow I have been using a circular saw that has no key slot in the motor drive shaft. Confuscious says, no slot and no key then no drive. Has anyone any idea what was driving the saw initially as for the life of me I can see no explanation as to how it could even cut through butter in it's current state. [/QUOTE]
